  • Patent number: 11175559
    Abstract: An electrochromic device is provided. The electrochromic device includes a first electrode, a second electrode opposed to the first electrode at an interval, and an electrochromic layer between the first electrode and the second electrode. The electrochromic layer contains an electrochromic material and a first ion-conducting material partially comprising a non-ion-conducting portion that does not conduct ions. The non-ion-conducting portion comprises a molecular unit structure having an atomic arrangement in which 8 or more atoms having a valence of 2 or more are bonded with each other. The atoms comprise heteroatoms in a number of 15% or less based on a total number of the atoms.
